ILLUMINATED SIGN, FAGIES, ANDTHE LIKE.

Application filed .Tune 22, 1920. Serial No. 390,763.

`band oi' bands, are caused to travel relatively to one another in parallel planes between the source ci light and the transparency or sign to be illuminated so as to produce varied colored effects.

N ow according to the present invention the screens used are formed of colored openmesh material adapted to give simultaneously almost infinite variations of color and (or) markings as of watered silk, the combination giving the whole a somewhat iridesceiit effect. The screens may also preierably be arranged around vertical rollers enabling a signto be provided having two or more illuminated sides.

In carrying the invention into practical eiiect the device may conveniently comprise a box or casing having one or more sides uniormly illuminated.

The sides of the box not illuminated are preferably painted dead black or coated with any suitable non-reflecting material. The characters forming the sign are suitably either stenciled in metal or other suitable material or left transparent on an opaque background or made opaque on a transparent background. l/Vhen more than one side is to be illuminated, between the source or sources of light and the illuminated sides of the box or case conveniently two thicknesses of colored open-square-mesh material may be caused to move laterally in parallel planes l in two concentric endless bands moving parallel to the illuminated sides at slightly diftering rates of speed, by means of rollers or spindles. Between the opposite illuminated double thicknesses of open-squaremesh material is a dividing wall or partition painted black, or coated with any suitable non-reflecting material. When one side only7 is to be. illuminated, between the source or sources of light and the illuminated side of the box or case conveniently two thicknesses of colored open-square-mesh material may be caused to move laterally in parallel planes in one endless band moving parallel to the illuminated side by means of rollers or spindies. The inner side of the `endless band may be brought into the necessary adjustment with the o or guides.

In order` that my said invention may be more clearly understoodand more readily ca rried into eiiect it is hereinafter describedv with reference to the accompanying sheet ofk drawings in which Figure l is a front 4elevation of an adver- Patentea July 2e, 192i.;

ter side by means of rodsl tisingu sign having more than one side illuminated; l l" Fig. 2 is a section on the line 2-2 of Fig. 3 is a plan;

Fig. 4 is a plan of a sign having onlyfone side illuminated, and

section on the line 5-5 of Fig. 5 is a Fig. 4.

As shown the improved sign comprises sides b stenciled or painted to leave the characters bof the sign transparent on an opaque ground or opaque on a transparent ground.

rIhe source or sources-of light o would preferably `be arranged in such a position that direct rays are not visible through the transparent characters Zi and behind the -'colored material Z from the spectators point of view. In a sign having more than one side illuminated as in Figs. 1 to 3, on four vertically arranged outer rollers or spindles e would be mounted an endless band al of suitably colored open-square-mesh material, such as silk, voile, organdy, leno, muslin, or gauze. On four inner rollers or spindles f would be mounted a second endless band cl of the same material, and having the same size mesh. Both these bands d d would be caused to move laterally at slightly different power and belting ory diagrammatically in the simultaneous constantly' moving striated covered with either Vgeometric patterns or irregular splotches of various colors.v for ad- The devie'e'couldA be used as Aa sign vertising or similar purposes.. TWhen illuminated from within in the manner described, the effect to the spectator is that oi a constantlyl blending variety of colors, with markings as of watered silk in almost infl-V nite variety. r V

j In a sign where onlyoneV side is required to be illuminated as in Figs. a and 5 only x Vone endless band lcl of open-square-mesh material would be employed, the inner side oi which would move'in parallel planes with, butin 4the opposite, direction to, the outer side as vwill-be readily understood. f The in v11er side of the band'rwould bebrought into the necessary proximity'to the outer side in orderto obtain the necessary striated or wa'- terA-mark eiectv by rods or guides y' as shown. The unilluminated sides oi the boX would be painted Ablack or coated with any suitableY non-reflecting material and the source or4 sources of light c also placed out of thefdi-r n rect lline'oi" vision of thespectator as previ-` f invention in suohposition with regard to the placing ously described.

to use belting l.or 'gearing' h for driving, therollersf or spindles e -as any Source of power and any suitable form of transmission may be employed.

The source or sources of light are placed of the sign that ydirect rays are not visible behind the stenciled or transparent portions of lthe vsign or in the spectators line of vision. t Y

' The dividingV wall or partition a' would only run longitudinally down the center It is not essential to thisv are stationary and slightly spaced from each other the novel iridescent and watered silk effect will be obtained as the observerpasses in front of the device due to changing viewn point. Y Y VWhat I claim is 1,An advertising and displayapparatus including a transparent character bearing section, a source 'of .light Vand a plurality of independent colored screens moving in par- Y allel planes and at diierentfrates of speed` and between said source of light and chary acter Vbearing section.

2. An advertising and display apparatus including aV transparent character bearing section, a source of light and a plurality of independent colored screensr` moving in parallel planes between said source of light and character bearing section, and a nonfre'ilect! king back ground.

3. An v'illuminated advertising and display apparatus' including a'character bearing transparent section, a source of light and a plurality of fabric'screens interposed between'the source oi' light and character bearing section and moving in Vopposite directions at different rates of speed and'V inparallel planes.
